TO ALL WHOM I'l MAY CONCERN Beit known that I, J. D. ISRAEL, of Utica, in the county ofVan Buren, in the State of Iowa, have invented a new and useful Improvement in Post-Drivers; and I do hereby declare that the following is a full, clear, and exact description of the same,reference being had to the annexed drawings, making part of 'this specification, in which- Figure 1 is a perspective view.

Figure?. is a vertical section of the top.

Figure 3, an elevation of the hoisting-apparatus.

The same letters in all the figures are used to indicate the same parts. ,i

My improvement consists in a novel arrangement of parts to form an adjustable and portable driver, for putting down posts for fences and 'other purposes on the land.'

In the annexed drawings, A is a piece of timber, to which the pieces Al and A2 are bolted, so as to form a tripod, as shown. The leg A is longer'than the legs AV1 and A", and it has a wheel, a, in its foot, on which the machine can be trundled from place to place. The box B is adjustably pivoted to the top of the leg A1, and it contains the hammer C, which moves freely up and down in the box, being directed by pins C passing ,through slots in the box. YA grooved sheave, D,- is placed in the top of the leg A, and over itvpasses a rope, E, upon which the hammer is suspended. This rope is fastened to a sleeve, F, which turns freely on the round brace I2. The hand-wheel H is hung on the end of said brace. A bent lever, H, passing through the slotted spoke G', is hinged to lthe huh of the wheel, and so formed that it may be introduced into oneof a series of notches F', out in the end of the sleeve F, so as to form a rigidconneetion of the said Wheel and sleeve. l' lhe legs are braced by three braces, I Il I2, of which the two former are constructed with a series of holes, by one of which they may be connected with the leg A1 by a pin, so as to permit the height of the driver to be regulated,'or `the tripod accommodated to inequalities of the ground, ,by setting the /leg A1 nearer to o r further from the others. The brace I is carried over the sleeve F, so as to form a guide for the rope E, and keep it from running oi from the sleeve. l

The machine is operated in the following manner: The tripod being so moved as to bring the hammer over the post to be driven, and the height properly regulated, the wheel Gr and sleeve F are then` to be connected by the lever H, and the weight to be raised by turning the hand-wheel and windingthe rope around the sleeve` When the hammer is sufficiently elevated, the lever His disengaged, freeing the sleeve, and permitting the weight to fall on to the head of the post.

What I claim as my invention, and desire to secure by Letters Patent, is-

The combination of the tripod, the hammer, the rope, the sleeve, the hand-wheel, and the lever, constructed and arranged substantially as described.

In testimony whereof, Ihave signed my name to this specification inthe presence of two subscribing witnesses.
